Frequently asked questions
Frequently asked questions about publishing agreement calculator
Rights typically revert when the book goes out of print or the contract term expires without renewal. Traditional publishing contracts may include "in perpetuity" clauses, but modern agreements often revert rights after 3-7 years if sales fall below minimum thresholds.
Option periods (typically 30-90 days after delivery of the current work) give publishers the right of first refusal on your next book. During this window, you must submit your next manuscript to them before shopping it elsewhere.
Royalty accounting periods are typically quarterly or semi-annual, with payment 30-90 days after period close. For example, Q1 royalties (Jan-Mar) might be calculated in April and paid in May or June.
Early termination is difficult unless the publisher breaches terms (such as failing to publish within 12-24 months or letting the work go out of print). Some contracts include performance-based exit clauses if sales targets are not met.
